The new one will patch directly the existing file. Did you see my latest patch (v4l_fix.patch)? It fixed the field sync stuff and cleaned up the code. Did anyone see the patch? I haven't received any comments on it nor has it appeared in cvs. > I also have an idea how to tell the provider what it should do > (grabbing/overlay) at runtime.

I'm not sure what benefit that would have. When AGP surfaces become supported it might be useful depending on how the surface allocation is done. If v4l would allow user space dma and/or syncing with VIDIOCCAPTURE things would be so much nicer. How does v4l2 handle this? AFAIK at least parts of it are going into 2.5. -- Ville Syrjälä email@example.com http://www.sci.fi/~syrjala/ -- Info: To unsubscribe send a mail to firstname.lastname@example.org with "unsubscribe directfb-dev" as subject.
